COMBINED HORSESHOE-SHARPENER, DRILL,AND SAW-GUMMER.

SPECIFICATION forming part of Letters Patent No. 422,045, dated February25, 1890.

Application filed June29, 1889. $erial No. 316,038. (No model.)

To caZZ whom it may concern:

Be it known that I, FRANK L. ADAMS, a citizen of the United States,residing at Saginaw, 1n the county of Saginaw and State of Michigan,have invented certain new and useful Improvements in Combined Drill,Horseshoe- Sharpener, and Saw-Grimmer; and I do hereby declare that thefollowing is a full, clear, and exact description of the same, referencebelng had to the annexed drawings, making a part of this specification,and to the letters of reference marked thereon.

This invention relates to certain new and useful improvements incombined drills, saw- J gummers, and shoe-sharpeners, and it has for itsobjects to provide a machine by means of WhlCll articles may be drilled,saws gummed, and horseshoes sharpened without any material alteration inthe parts of the machine; also to so construct and arrange the partsthat the various operations maybe carried out with ease and rapidity.

The invention consists in the peculiar (30111 bmations, and theconstruction, arrangement, and adaptation of parts, all as more fullyhereinafter described, shown in the drawings, and then particularlypointed out in the appended claims.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, and in which- Figure 1 is a side elevation of a machineembodying my improvements. Fig. 2 is a top plan of the same. Fig. 3 is adetached perspective view of the saw-rest. Fig. at is a side elevationof a portion. of the drill-operating mechanism detached.

Like letters of reference indicate like parts throughout the severalviews.

Referring now to the details of the drawings by letter, A designates asuitable frame designed to support the operating parts.

Bis a transverse shaft journaled in suitable bearings on thelongitudinal timbers of the frame. This shaft carries the pulley G,

to which motion is designed to be imparted either by means of the crankand handle D on the extended end of said shaft or by means of treadlesarranged as follows: Pivoted at its rear end, as at a, to the frame is atreadle b, the other end of which extends to within convenient reach ofthe operator. A shorter treadle c is pivoted between its ends, as at d,

to the front part of the frame, and between Fulcrumed onthe shaft B is alever E, the.

rear end of which is connected with the frame A by means of a suitablespring F, and between thcse levers E, (there being one near each side ofthe machine,) near the front end thereof, is journaled the transverseshaft G, carrying the emery-wheel Hand pulley I.

J is an endless belt connecting the pulley O with the pulley I, wherebymotion is communicated from the pulley O to the pulley I and to theemery-wheel. The pulley I is preferably provided with projections 71 toincrease its grip on the belt.

Detachably secured to the front part of the frame A is the saw-restcarried by a base K, attached to the frame by means of suitablefastenings, which may be readily removed when the device is to be usedas a shoe-sharpener. The rest proper consists of a plate L,

attached to the outer edge of the base and provided with a guide-rod i,on which the upper plate M is designed to be longitudinally adj ustaloleby means of the eyes j, the said upper plate being yieldingly supportedon the under plate by means of springs k. v lVith the parts in theposition in which they are shown in full lines in Fig. l the same aredesigned to be employed for gunnning saws. The saw is placed upon thesaw-rest and the gummer or emery-wheel brought into contact therewith bythe manipulation of the levers E.

When to be used for sharpening horseshoes the saw-rest and its base isdetached and the parts brought into the position in which they are shownby dotted lines in Fig. 1, the shoes being designed to be sharpenedwithout removing them from the feet of the horse.

N is a bracket or arm attached to the frame A, near the front endthereof, and carrying at the upper end thereof a transverse shaft 0, 011which is a pulley P, in line with a pulley Q on the shaft B, the twopulleys being U is the holder for the article to be operated upon by thedrill q carried by the drillstock.

V is a lever pivoted at 1' to a standard on the frame, and having oneend connected to the frame by means of a spring 8. This lever isdesigned to regulate the position of the drill.

It will be seen from the above description that I have devised a machinewhich is adapted for the various purposes set forth without materiallyaltering any of the parts, and if so desired, articles may be drilledand horseshoes sharpened at the same time.

What I claim as new is- 1. The combination, with the frame, of thelevers E fulcrumed on the driving-shaft, an emery-wheel carried by ashaft on said levers, and means for imparting motion to said emerywheel, whether the same be in a raised or depressed position,substantially as herein shown and described.

2. The combination, with the frame and drive-shaft, and pulley, of theemery-wheel operated from connections with the driveshaft, and thesaw-rest operating in conjunction with the emery-wheel, substantially asshown and described.

short lever pivoted to the frame between its ends, and also pivotallyconnected between its ends to the long lever, the crank on thedrive-shaft, and the rod connecting the rear end of the short lever withsaid crank, substantially as shown and described.

5. The combination, with the frame, the

drive-shaft, and the pulleys on said shaft, of 'j the emery wheel drivenfrom connections with said shaft, and the drill driven also by of twowitn esses.

FRANK L. ADAMS.
